This indicates corrupted data --- specifically, a trashed transaction ID
in a row header.  In all the cases I've been able to examine, this was
just the first symptom of more widespread corruption (usually, a whole
disk page is trashed).  I recommend checking for hardware problems;
you may have bad RAM or a flaky disk drive or cable.
